ActiveInorganic chemicas for industrial use - General method for the determination of whiteness
无机化工产品白度测定的通用方法
Application Summary AI generated
This standard specifies a general method for measuring the whiteness of inorganic chemical products, using a photoelectric whiteness meter to quantify the reflectance of a sample relative to a standard white plate. It is applied in the quality control and testing of industrial inorganic chemicals, such as pigments, fillers, and salts, where whiteness is a key appearance indicator. The method ensures consistent evaluation across manufacturers and laboratories for products used in coatings, plastics, paper, and construction materials.
